I still stand by FRK, next to HP largest cell, Corby did it with a M 100 much
more difficult. I started on a FRK but because of a macular hole in my left eye
had to stop.First test should be to change time constant and monitor
performance.Remember the outstanding performance of the HP is do to the fact
that the optical unit takes over somewhere around 0.1 seconds.FRK is well
documented and easy to work on.We have pictures have to compress to attach to
time nuts or contact me off list.Again if some one wants to take over please
contact me directBert Kehren
